ABSTRACT
This study was aimed to optimize the extraction process of resveratrol by central composite design (CCD) and response surface method (RSM), based on the result of single factor experiment. Resveratrol was extracted from Polygonum cuspidatum by water bath extraction of organic solvent. And content of resveratrol was taken as index in the investigation of solvent concentration effect, extraction time and solvent content on extraction process. The results showed that the optimum condition was 12.7 times amount of 72.0% ethanol and extract for 2 times under the temperature of 50℃, 1.1 h for each time; the average deviation between the maximum theoretical value and measured value was 0.83%. It was concluded that this extraction process was highly predictive, which provided experimental evidence for the industrial production of P. cuspidatum extraction.
